I don't think that 35$ are too prizey, you get the cartridge+Mega CD including the booklet and box. Sounds fair enough.

It's a fair price for the package, but for someone who doesn't care too much about the goodies and just wants to have the game (MegaCD preferred ), it's a bit expensive. For 20$ it's a sure buy, but for 35$ I really must think about it.
